fo /LZZ whom it may concern.-

Be it known that I, CHARLES HANrMANN, a citizen of the United States,residing at Flushing, in the county of Queens and State of New York,haveV invented certain new and useful Improvements in Bench-Vises, ofwhich the following is a full, clear, and exact specification, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon.

My invention has relation to vises such as are employed by mechanics andintended to hold articles or materials while they are being worked upon.These vises are usually attached to some fixed support, as a bench, andthey are ordinarily known as "bench-vises. Of these bench-vises thereare many varieties suitable for holding different kinds of work andoperative in different ways, and it is to a variety now come to becommonly known as my invention isvparticularly directed. Thequick-action or rapid-transit vises are such as -permit of the movablehead being adjusted rapidly back and forth without the necessity ofdepending upon the screw or independently of the screw when the latteris out of. engagement with the means by or through which it causes thehead to move back and forth.

The principal object of my invention is to provide or produce aquick-action or rapidtransitbench-vise wherein the grip of the screw iseffected or relieved by asimple and comparatively slight turning ofthescrew-shaft itself, wherein the parts are few and simple and easy ofconstruction and easy to mount in place, and wherein the working partsare durable and substantial, reliable and efficient in action, and notliable to get out of order.

To accomplish all of the foregoing objects and to secure other andfurther advantages in the matters of construction, operation,application, and use, my improvements involve certain novel and usefulpeculiarities of construction, relative arrangements or combinations ofparts, and princi ples of operation, all of which will be herein firstfully described and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, I haveshown my improvements as applied in connection with a particular form ofbench-vise which is ordinarily called a cabinet makers vise orWoodworkers vise; but it should be understood that this selection isonly for convenience of illustration and that my improvements areequally applicable in connection with any other variety of bench-vise.

Figure l is a section and elevation of one form of a vise having myimprovements applied thereto, the view being taken on a plane throughthe axis of the shaft or vise-screw and the working parts being shown inthe position which they occupy when clamping any piece of work or whenthe movable vise-head is forced up close against the stationary head.Fig. Q is a cross-section and elevation on a plane through line t a ofFig. l and looking in the direction of the adjacent arrows. Fig. 3 is across-section and elevation on a plane through line b of Fig. I andlooking in the direction of the adjacent arrows, but omitting thescrew-shaft and screw. Fig. 4L is a crosssection and elevation on aplane through line c c of Fig. 'l and looking in the direction of theadjacent arrows. Fig. 5 is a side elevation and partial sectional viewof the screw as it appears when dismounted or disconnected from theshaft and other parts, this view being enlarged beyond the previousviews.

In all the figures like letters of reference wherever they occurindicate corresponding parts.

A is the front or movable head of the vise, which is intended to travelback and forth and to operate in connection with the other head B, whichis stationary and usually constitutes a portion of the body of the vise.

C represents a fragment of a bench or other object upon which the visemay be mounted in any suitable way, the location of the visebodyinrespect to this bench, as shown in the drawings, being merely thatadopted in connection with cabinet-makers or woodworkers vises.

D is the main portion of the body of the vise, which carries thestationary head and accommodates the slide-bar, which carries themovable head. The slide-bar (represented at E) is fitted to slideeasily, but with considerable accuracy, in the body of the vise,carrying with it the movable head and screw-shaft and its handle.` Onthe inner side of the slide-bar is a rack, (represented at 62,) the samebeing formed with the slide-bar or applied thereto in asubstantialmanner and being fitted to engage with the screw by which the slide-baris to be'moved.

IOO

F is the screw, which is made amply strong and which is calculated to beturned by the screw-shaft Gr. The shaft G is slotted or channeled orkey-seated, as at e, and a key f applied in the screw F permits theshaftG to slide back and forth within the screw, but compels the screwto turn whenever the shaft is turned.

H is a suitable head for the shaft, the same being fixed on the outerend of the shaft in some substantial manner or by some su bstantialmeans, and in this the handle or lever H is mounted, as is usual invises.

When the screw F is in engagement with the rack d, the turning of theshaft Gr, and through it the screw F, will effect the retraction oradvancement of the slide-bar E with respect to the body of the vise, andtherefore open or close the vise-jaws A and B. According to myinvention'the screw and the shaft are arranged to be dropped down or thescrew, in other words, to be carried out of its position for engagementwith the rack, and when the rack and the screw are out of engagement thebar E, carrying the head A, may be moved back and forth rapidly andwithout depending on the slow turning of the screw.

That the screw may be thrown into engagement with its rack or permittedto move out of said engagement by the simple turning of the screw-shaft,Iprovidethe shaft-head with one, two, or more recesses, as at g, thesame having an inclined side, so that the turning of the screw-shaft inone direction will cause the head and adjacent end of the screw-shaft torise or be forced up on a correspondingly-inclined or other suitableprojection, as t, which is aflixed to or forms part of theslidebar. Thescrew F is similarly recessed, as at g g, and these recessed portions ofthe screw ride upon a suitable block or other projection, as L, appliedto the lower portion of the vise-body. The notches or recesses g and gare of depth suficient so that when the screw drops down or when it isin its lowermost position it is entirely free from engagement with therack, and the slide-bar is then free to be moved out or in rapidly andas occasion may require.

The screw is located between two abutments, as at I and K, iiXed withrespect to the body of the vise, and these, as also the front wall ofthe slide-bar, are provided with openings, as o 0, sufficient to enablethe screw-shaft to rise and fall within them as may be necessary. Acollar on the screw-shaft (shown at L) compels the shaft to travel withthe slide-bar.

When the handle H or the shaft-head H is turned in the direction toscrew up the movable vise-head, the screw turns with it and is forced upto engaging position by the blocks or projections 7L t'. Then on furtherturning of the screw-shaft and screw the slidebar is moved by the screw,the adjacent end of the screw then bearing against the abutment K. Thisbearing is ordinarily sufficient to prevent the screw from dropping outof engagement with the rack as the shaft is further turned: but I findit desirable to provide the screw with a slight projection, as at z',and to recess the abutment K, as at 7c, suflciently to take thisprojection, so that when the screw is elevated to its engaging positionand commences to move the rack and the slide-bar connected therewith theprojection 'a' will be forced into this recess 7c in the abutment K, andthe, screw will thus be prevented from descending until it is turned inthe opposite direction. On turning the screw-shaft in the oppositedirection the screw will by its contact with the rack be carried forwardenough to relieve the projecting portion c' from the recess 7c, and assoon as the notches g g reach positions over the respective projections/L /t the screw and its shaft will drop down and the screw be disengagedfrom the rack.

From'the foregoing it will be readily understood that in order totighten the vise by use of the screw it is only necessary to turn theshaft in the proper direction and that to disengage the parts so thatthe slide-bar will be free to be moved back and forth without turningthe screw it is only necessary to turn the screw-shaft in the directionusual for releasing the work.

One notch g or g will be sufficient, but would necessitate a completerevolution of the vise-shaft in order to bring the parts into workingengagement or to release them. By employing the notches in pairs, asindicated,

IOO

manifestly only one-half turn of the screwshaft is all that will benecessary to effect the desired engagement or disengagement, and if itshould be desired more of these notches may be employed; but the`half-turn of the screw-shaft is deemed none too extensive a movement toeffect the desired results.

The threads of the screw for the length of the recess gf are preferablyblunted or cut away, as indicated in Fig. 5, so that they will rideeasily on the projection 7L' and without cutting into the latter, andthe height of projection i is made to compensate for this cutting awayof the screw, so that the screw and its shaft will rise and fallparallel with the rack.

The devices being constructed and arranged substantially in accordancewith the foregoing explanations will be found to admirably answer allthe purposes or objects of the invention hereinbefore alluded to.

Having now fully described my invention, what I claim as new herein, anddesire to secure by Letters Patent, is-

1. In a bench-vise having jaws, the combination with the slide-barcarrying the movable head or jaw, of a screw-rack in said bar, a screwfor engagement with the rack and a shaft for turning the screw, thescrew and its IIO shaft or permit them to drop, substantially shaftbeing arranged to be raised and lowered by turning the shaft,substantially in the manner and for the purposes set forth.

2. In a bench-vise having jaws, the combination with the screw-shaft andscrew mounted and keyed to each other so that one may move within theother, the head of the shaft and the screw being notched as explained,and the projections arranged to elevate the screw and as and for thepurposes set forth.

3. The combination with the vise-jaws and a screw notched as explained,of the shaft for turning said' screw and made movable therein, andabutments connected with the vise-body and arranged to permit the screwand its shaft to rise and fall, substantially as set forth.

4. The combination of the vise,- jaws, the screw', the screw-rack, thescrew-shaft moving longitudinally through the screw, and the abutments,the screw being provided with a projection on one end and the adjacentabutment being recessed to receive this projection, substantially asshown and described.

5. ln a bench-vise having jaws, the screw notched as explained, aprojection on the visebody for entering said notch and a shaft forturning the screw, the threads of the screw `being cut away to ride onthe top of the projection,the parts being combined and arrangedsubstantially as set forth.

In testimony whereof l have signed my name to this specification in thepresence of two subscribing witnesses.
